Commercial Facilities & HVAC
Hydronic and HVAC instrument calibration for commercial facilities
Building automation systems make decisions based on flow, pressure, and temperature readings from the mechanical room. We calibrate and repair those instruments on chilled-water, heating-water, and pump systems in commercial buildings, campuses, and institutional facilities.

Where calibration shows up
The instruments your building automation relies on
Most HVAC instruments report to a building automation system, so errors are rarely visible until comfort or energy use changes.
Chilled-water systems
Flow meters and temperature sensors on chillers and distribution loops, used for capacity control and energy tracking.
Heating-water and hydronic loops
Temperature and pressure instruments on boilers, heat exchangers, and hydronic distribution.
Pumps and differential pressure
DP transmitters and gauges that drive variable-speed pump control and show filter and coil condition.
Energy and tenant metering
Flow and temperature pairs used to calculate thermal energy for billing, benchmarking, or cost allocation.
Common instruments
Instruments we calibrate and repair for this work
Commercial mechanical rooms use a familiar set of hydronic instruments. These are the types we calibrate and repair most often.
Services
What we handle, from first check to replacement
We work with facility managers and mechanical contractors and can schedule visits around occupied hours.
On-site calibration
Calibration of flow, pressure, and temperature instruments in the mechanical room, with results you can compare against your building automation readings.
Verification
Documented checks that confirm sensors and meters are within tolerance, useful during retro-commissioning or energy audits.
Troubleshooting
Finding the cause of flow readings that do not match pump performance, unstable differential pressure control, or temperature sensors that disagree.
Repair
Repair of flow meters, transmitters, and sensors, followed by calibration before they go back into service.
Equipment sales
Replacement flow meters, sensors, and transmitters compatible with your existing piping and building automation signals.
Calibration program
Why calibration matters
In commercial buildings, instrument errors usually appear as comfort complaints or higher energy bills before anyone suspects a sensor.
01
Accuracy
Flow and temperature data drive chiller staging, pump speed, and energy reports. Calibration keeps that data trustworthy.
02
Reliability
Sensors that read correctly let the automation system respond to real conditions instead of chasing a bad signal.
03
Reduced downtime
Finding a failing sensor during a routine visit avoids an emergency call when a system stops responding on a hot day.
04
Documentation
Calibration certificates support commissioning records and energy programs, and can be viewed, downloaded, and shared in the online portal.
